13b vs ls1
you have to take into effect the twin turbos and all the supporting pieces. i dont know if it is an iron block or not but that would effect it. that engine weight includes turbo plumbing, intercoolers, and all that jazz. i saw those numbes when compact car (i know) compared an rx7 twin turbo with an rx7 that had an ls1 and an ls1 camaro. those were the numbers they quoted, even with their obvious bias

LS1 is a SMALL motor. all aluminum heads, block and composite intake, makes up a very small and light motor
